Because of the limited pharmacological treatment options available, many patients build up a tolerance to prescribed medicine. Additionally, traditional acupuncture requires patients to make repeat appointments and a fear of needles may make it undesirable for many patients. The wireless, needleless device tested in the study was designed by Jiande Chen, PhD, professor at the University of Texas' Medical Branch at Galveston, and allows clinicians to tailor the frequency and amplitude of the electrical waves used to stimulate acupuncture points.
Funded by grants from the National Institutes of Health, patients were instructed to spend 240 minutes each day using the device on designated spots on the body. They kept a detailed diary tracking specific gastroparesis symptoms and the number of heartburn episodes per day.
Dr. McCallum worked with fellow Texas Tech professor Irene Sarosiek, MD, senior author of this project, to analyze results of a four-week period of use of the device. Compared to the placebo group, the device significantly improved five out of nine gastroparesis symptoms vomiting was reduced by 39 percent, nausea by 30 percent and bloating by 21 percent. The number of heartburn episodes decreased significantly when patients utilized active stimulation.
"These exciting initial results have great potential for patients," Dr. McCallum said. "With the customizable features of the device, we can explore fine-tuning the therapy to directly target specific symptoms."
